A concurrent unregister can delete and free that entry in the gap, leaving the handler to dereference stale memory.</p> <p>Copy the callback pointer and callback data while notify_lock is still held and invoke the callback only after the lock is dropped. This keeps the existing callback execution model while removing the use-after-free window in both the framework and non-framework notification paths.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>firmware: arm_ffa: Snapshot notifier callbacks under lock</p> <p>Both notification handlers currently look up a notifier callback under notify_lock, drop the lock, and then dereference the returned notifier entry.
